    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timing uncertainty; clock jitter; Sigma-Delta Analog-to-Digital Converter; sampling; clock generation; power-supply noise; substrate noise; Electronics; Elektronik;

    Abstract : Denna avhandling presenterar en undersökning av orsakerna och effekterna av timingosäkerhet i Sigma-Delta Analog-Digital-Omvandlare, med speciellt fokus på Sigma-Delta av den switchade kapacitanstypen. Det undersökta området för orsakerna till timingosäkerhet är digital klockgenerering och området för effekterna är sampling. READ MORE

  3. 3. Continuous-Time Delta-Sigma Modulators for Ultra-Low-Power Radios

    Author : Dejan Radjen; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Delta-Sigma; continuous-time; analog-to-digital; ultra-low-power; clock jitter; single operational amplifier; SAR quantizer;

    Abstract : The modern small devices of today require cheap low power radio frequency (RF) transceivers that can provide reliable connectivity at all times. In an RF transceiver, the analog-to-digital converter (ADC) is one of the most important parts and it is also one of the main power consumers. READ MORE

  4. 4. Charge Sampling Circuits and A/D Converters - Theory and Experiments

    Author : Gang Xu; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipelined A D converter; sigma-delta modulator; differential difference comparator; 2-step A D converter; FIR filter; analog filter; thermal noise; clock jitter; sub-sampling; RF sampling; current-mode sampling; Charge samling; A D converter; flexible A D converter; Electronics and Electrical technology; Elektronik och elektroteknik;

    Abstract : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. READ MORE
